"A candid phone-camera wide selfie of a 20s woman with shoulder-length wavy dark hair wearing a beige trench coat, white tee, and sneakers, standing on a city sidewalk and glancing near the lens while holding an iced coffee mid-step. Behind her, a striking modern glass-and-concrete building exterior shot from a dramatic low angle with strong leading lines and reflections, golden hour sunlight and long shadows across the façade. Authentic Instagram story vibe with natural lighting, slight motion blur, casual unposed framing, real urban street details (bike rack, crosswalk, pedestrians in the distance)."
